CS 107 - Introduction to Scientific Computation Homework #12

0. Preparatory Reading: You will benefit from reviewing the portions of Java we've covered in the CS 111 Java Summary.

1. Greetings:  Create a Java program Greetings.java that prompts the user to input their name, and prints "Hello, <name>!".

2. Circle Math:  Create a Java program CircleMath.java that prompts the user to input a double radius, and prints the double diameter, circumference, and area. 

Note: You can calculate the square of radius by using either radius * radius or Math.pow(radius, 2).

Example Transcript (input underlined):

Radius? 10
     diameter = 20.000000
circumference = 62.831853
         area = 314.159265 

3. Division:  Create a program Division.java that has the user enter two integers, which are then used to compute both the floating point and integer division results as follows (user input underlined):

Please enter integer a: 9
Please enter integer b: 4
Floating point division: a/b = 2.250000
Integer division: a/b = 2 remainder 1

4. Circle: Define a class Circle (in Circle.java) with

• a constructor that takes a radius,
• getRadius and setRadius methods,
• a getArea method, and
• a getCircumference method.
